Application filed March 6,1907. Serial No. 360,941.

To all whom it may concern:

Be it known that 1, WILLIAM H. McNU'r'r,

' specification.

This invention has reference to valved spouts for var ous kinds of cansor receptacles, and especially relates to what are sometimes termedsquirt-cans or oil-cans, al-

though it is especially designed to be used for volatile and explosivefluids like gasolene fluids are employed for cleaning clothing and ornaphtha; that are used by printers, for cleaning type and various otherthings; and also used by tailors and others where such fabrics.

It is an object of the invention to provide a spout member for a cancontaining a valve that is normally retained tightly closed and willremain open only While pressure is exerted thereon by the user, thevalve closing immediately upon the pressure being removed.

A further object of the invention is to pro-. vide a form of valvedspout in which when; the valve is closed after use, such gasolenethatdoes not run out of the spout will pass back into the can, and notremain in the spout member. And in conjunction therewith safety membersin the nature of perforated plates or wire gauze are provided on .bothsides of the val'vein the spout member.

In the accompanying drawings representing one embodiment of the presentinvention,

Figure 1 illustrates a filler can in side elevation. Fig. 2 is afragmentary view enlarged showing in section the valve spout. Fig. 3 isa section on the line 3-3 of Fig. 2. Fig. 4 is an enlarged detail viewof a portion of the spout member, and Fig. 5 is a fragmentary plan viewof the parts shown in Fig. 2.

The invention is shown in Fig. 1 as applied to a can 8 having a handle 9and a filling cap 10 at the top. The spout member denoted generally by11 is shpwn secured to the can top adjacent the cap 10.

The spout member comprises essentially two telescoping tubes, one ofwhich carries the valve seat, while the other is secured to the valvewhereby the sliding movement will open and close the valve on its seat.Means such as a coil's ring are provided to normally retain the va veclosed on its seat.

When the members are shifted against the force of the spring, the 'valveis opened and the gasolene can be poured'out upon inverting the can butimmediately upon release of the telescoping tube member; the spring willclose the valve and no -more gasolene can 1 flow out, and its vaporsareprevented from escaping, as well as flame 1s.prevented from access tothe vapor in the can.

In the construction herein illustrated, the top of the can has athreaded opening 12, in

which screws a tube member having an enlarged chamber at itsintermediate portion. The tube comprises a neck portion 1S atone endconnected with a threadedneck portion 14 at the other end, by anenlarged portion 15 constituting a valve chamber. The neck 14 isthreaded. to screwinto the threaded openinIg;.12 ini the can, ,that'maybe elongated to provide a suficient threading,portion. The neck isscrewed into the can until the bottom of the'chamb'er 15 rests .on topof the, can.

A. tube 16 telescopes on'the neck portion 13 and may be provided with apouring extension 17 that is shown curved and somewhat funnel shaped orreduced. A valve in the form of a disk 1.8 operatesiin the chamber 15 bybeing secured to a stem'19, connected at the top by a cross bar 20 withthe-outer telescoping tube 16; the bar 20 passing through slots 21 and22 in the neck tube 13,- permitting the outer tube' to slide to-move thevalve to and from its seat. A rim 23 is preferably provided at the topof thechamber- 15, being practically an extension into the chamber ofthe neck 13, which forms the seat for the valve 18; the valve beingpreferably provided with leather or other suitable washer for tightlyclosing the opening. The sliding tube 16 may be provided with wings, 24and 25 for engagement by tirefirigers ofthe operator to move the valveto open position; its movement being limited by the engagement of thesewings with the top of the chambered member 15-as indicated in brokenlines in Fig. 2. The valve is normally retained closed by a spring. Inthe construction illustrated a coil spring 26 surrounding the valve stem19 below the valve, engages an apertured plate 27 screwed into the lowerneck 14, the plate having a central bore through which the valve rodslides. The minute openings in this plate form a safety devicepreventing flame or heat from igniting vapor in the vessel, If desiredagauze cone 28 may be provided on1 the lower side of the ICO plate 27 fora similar purpose. A similar safet member 29 is also placed in theoutlet mem er 16, that may be either perforated through the spout tube.

metal or Wire gauze, preferably both.

From this construction it will lie seen that when it is desired to pourfrom t e can, it is. inverted and the valve opened by pressing on thewings on the slidingrmember, which will push the valve inward om itsseat, ermitting the gasolene toflow from the 0 amber Back-draft iseflectually prevented by the two safety members vprovided in the pouringdevice. The valve being released, will at once seat itself, theremaining gasolene will flow out of the telescoping tube members. Uponrighting the can, the gasolene remaining in the chamber portion '15 willflow down into the can through the erforated plate 27 and gauze 28.Should a 're or intense heat occur-near the can, the vapors formed arepermitted to es cape by meansof a fusible member provided below thevalve, preferably in the chamber 15. As shown in Fig. 4, a disk 30 issecured in an opening in the side of the chamber b a 'fusible ring 31,preferably of solder; he heat will melt this ring and the disk will blowout, permitting escape of the vapors generated. Yet should these vaporsignite they cannot back-fire into the can by reason of the aperturemembers 27 and 28.

Having thus described my invention, I claim: r

1. The combination with a can, ofv an outlet member secured at an openinin the can and having an intermediate chamo ered part, the

outlet member having a valve closing its admission to the outlet of thechamber. the outlet member having a telescoping portion connecting withsaid valve, a spring arrai'iged to press the valve against saidopening,'and apertured (liaphragms in the outlet:

2, The combination with'a can having an opening therein, of an outletmember comprising .a tubularportionha'ving an enlarged chamber atan'lntermediate part,- a valve opening in the can I opening therein, ofa tubular member having -a chamber at an intermediate portion and fittedinto said opening, a valve arranged to close the openin from the chamberinto the outlet portion 0 the tube, a plate within;-

nute openings extending across the opposite f ,PQIUOII of the tube, astem for said valve sliding in a bore in the latter'plate, a spout tubeshdln on the outlet portion said tube. a cross ar connecting the spoutmember with the valve stem, the inner telescoping member havin slotsthrough which the cross bar is slidab e to permit movement of thetelesco ing member to open and cl'o'sethe valve, an a coil spring on thevalve stembetween the apertured plate and the valve valve against itsseat.
